Hamburger press



C. S. GLENNY HAMBURGER PRESS March 22, 1960 Filed Jan. 14, 1957 CLARENCE S. GLENNY nited 2,929,099 HAMBURGER PRESS Clarence S. Glenny, Rockford, Ill., assignor to The Washburn Company, Worcester, Mass, a corporation of Massachusetts Application January 14, 1957, Serial No. 633,964 10 Claims. (Cl. 17-32) This invention relates to a utensil for use in forming ground meat into hamburger patties and has for its principal object the provision of a ring body of the correct diameter in relation to hamburger bun size, mounted by pressure on the back of the disk.

In the present design an annular inwardly projecting flange is provided on one side of the ring body on which a disk is arranged to be supported in direct engagement with the flange or in elevated relationship thereto by means of vertical ribs projecting inwardly from the inner periphery of the ring above the flange, the disk being adapted to rest on top of these ribs but having notches in its periphery arranged to receive the ribs and allow the disk to drop down onto the flange, whereby when the disk is disposed on top of the ribs a shallower recess is defined in the ring to accommodate a relatively thin patty, and, when it rests on the flange, a deeper recess is defined to accommodate a relatively thick patty.

The invention is illustrated in the accompanying drawing, in which:

Fig. 1 is a plan view of a hamburger press made in accordance with my invention, showing the disk resting on the flange, a portion of the disk being broken away to show the flange therebeneath, and a portion of the handle being broken away and shown in section to show the supporting shank of the ring frame which has a press fit in the handle;

Fig. 2 is a similar view with the disk elevated and -turned so as to shift the notches out of register with the ribs so that the disk is supported on their upper ends;

Fig. 3 is a cross-section in the plane of the line 3-3 of Fig. 2, showing the utensil set for use in making thin patties;

Fig. 4 is a similar view taken on line 44 of Fig. 1, showing the utensil set for use in making thick patties; :and

Fig. 5 is a sectional detail along the lines of 4 but showing a modified or alternative construction.

Similar reference numerals are applied to corresponding parts in these views.

Referring to the drawing, the reference numeral 5 designates a ring formed from a single strip of sheet metal, the opposite ends of which are joined together 'by a seam at 6 in a conventional manner. An annular inwardly projecting flange 7 is formed on the bottom of the ring to define an annular supporting ledge or shoulder for a sheet metal disk 8, the disk being adapted to rest directly on this shoulder or flange, as in Fig. 4, to define a deeper recess, indicated by dimension a, for use in the making of thicker patties A, or being adapted to be supported at three evenly circumferentially spaced points on the upper ends of three vertical ribs 9 in elevated relation to the flange, as in Fig. 3, to define a shallower recess, indicated by dimension b, for use in the making of thinner patties B, the ribs 9 being provided as integral inwardly projecting portions of the ring 5, all of the ribs being of the same length measured upwardly from the flange 7 so that the disk 8 is supported parallel to the flange 2,929,099 Patented Mar. 22, 1960 ice 7, as seen in Fig. 3. A wire ring frame 10 for supporting the ring 5 on a handle 11 is secured to the ring in the curled upper edge 12 thereof. The rounded edge 12 defines a flared entrance into the ring 5, as is evident in the sectional views, Figs. 3 and 4, and this facilitates entry of the close fitting disk 8. The spaced, substantially radial, outwardly projecting end portions 13 of the wire itihave their extremities 14 offset inwardly toward one another and welded together, as indicated at 15, to define a slightly resilient and compressible shank adapted to be pressed into an axial bore 16 provided therefor in the inner end of the handle 11 for the rigid support of the ing to scratch or cut the hands when using the utensil in the forming of hamburger patties with ground meat.

In operation, the sheet metal disk 8, which is disposed in the ring 5 and is of approximately the same diameter as the conventional hamburger bun, is inserted with a snug sliding fit into the ring resting either on top of the ribs 9 to form a thin patty, as indicated at B in Fig. 3, or on the flange 7 to form a thick patty, as indicated at A in Fig. 4. Notches 17 are provided in the periphery of the disk 8 in evenly circumferentially spaced relation, and it is only when they are in register with the ribs 9 (as in Figs. 1 and 4) that the disk can drop down onto the flange. In Figs. 2 and 3 the disk is turned so as to shift these notches out of register with the ribs. The patties can be made quite uniform in either thickness and one gets four of the thicker patties A out of one pound of ground meat, and eight of the thinner patties B out of one pound of ground meat. A spatula or the like may be used in filling the utensil evenly for either thickness of patty, and then the ring 5 is turned over by means of handle 11 and pressure is applied to the back of the disk 8 to remove it with the patty from the ring, whereupon the patty may then be easily stripped off the disk with the spatula directly into the frying pan. There are no crevices in which food or filth might collect, and hence it is an easy matter to keep the press clean and sanitary. The close sliding fit of the disk 8 in the ring 5 eliminates any likelihood of the disk falling out when the utensil is not in use, and hence there is no danger of the disk being lost or mislaid by reason of being separated from the utensil, and, since it remains an assembled part of the utensil, it is in no danger of becoming bent or battered by contact with other heavier utensils, and the utensil always remains in good shape and ready for instant use. While this utensil was designed primarily as a hamburger press it should be clear that it is not limited to that specific use. Utensils made along these same lines could be used for forming patties of any plastic food or other material.

In Fig. 5, the sheet metal disk 8 is the same as that of Figs. 1-4, having notches 17 in the periphery, which when disposed in registry with inwardly projecting ribs 9' formed on the sheet metal ring 5' permit the disk to drop down onto the top of an annular inwardly projecting bead 7' formed in the ring 5' below the ribs 9; this bead defining the annular shoulder otherwise defined by the flange 7 of the other construction. The bead 7 defines an annular groove 18 in the outer periphery of the ring in which to accommodate with a tight fit the wire ring frame 10 for supporting the ring 5 on a handle 11, in the same way as in the other form. The opposite sides of the ring 5' have rounded edges by reason of the curling of the edge portions of the ring, as indicated at 19, so that the flared entrance into the top of the ring is defined as in the other form and also so that there .are no raw edges left exposed, and, hence, nothing to scratch or cut the hands when using the utensil in the forming of hamburger patties from ground meat. The operauon of this utensil is the same as the other and,

I therefore, no further description is necessary.
